UNITED STATES ANDREW J. KERSHNER, OF CHICAGO, ILLINOIS.

WRENCH.

Application led February 16, 1923.

To all wlwm t may concern:

Be it known that I, ANDREW J. KERSHNER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in 1Wrenches, of which thefollowing is a specification.

This invention relates to wrenches, and an object of the invention is toprovide a solid substantial wrench st-ructure of the vise type, whichembodies a relatively large body iaving a rigid aw at one end thereof,along which body a movable jaw is mounted, the said movable jaw beinadjustable by rotation of a handle whic is in turn carried by a suitablecarrying structure pivotally connected to the rigid jaw carrying body.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawings whereinFig. l is a top plan of the improved wrench.

Fig. 2 is a longitudinal section through the wrench talzen on the line 22 of Fig. l.

Fig. 3 is a cross section taken on the line 3 3 of Fig. 1.

Fig. i is a cross section on the line 4 4 of Fig. l.

Referring more particularly to the drawings, the improved wrenchcomprises a body l which is substantially U shaped and has a jaw orwrench face 2 formed on the inner edge of its bight portion. The legs 3of the body 1 are provided with longitudinal slots 4; which serve asguideways for the ribs 5 formed on the edges of the movable block 6. Theblock 6 has a wrench jaw 7 formed thereon which cooperates with thewrench face or jaw 2. The substantially U shaped body l is attached, bymeans of rivets or suitable pins 8 to a block 9, to which block a handlest-ructure 10 is pivotally connected by means of the bolt 11 so as toassume limited angular positions for allowing Serial No. 619,475.

the wrench to be used in various positions. A feed screw 12 is connectedto the slidable block 6 as shown at 13 and it threadably engages throughthe stationary block 9. The .end of the feed screw 12 remote from theslidable block 6 is forked as shown at 14C and has an operating handlel5 pivotally connected thereto. The operating handle l5 is rotatablycarried by the handle structure l0 and it has a hand wheel 16 on itsouter end by means of which the handle l5 may be rotated for adjustingthe jaw 7 relative to the jaw 2. ,i

.It is, of course, to be understood that the invention may beconstructed in other manners and the parts associated in differentrelations and, therefore, I do not desire to be limited in any mannerexcept as set forth in the claims hereunto appended.

Having thus described my invention what I claim is l. In a wrench, asubstantially U shaped body having a wrench jaw on the inner edge of itsbight portion, a block slidably carried by the legs of said body, awrench aw carried by said block, a block rigidly attached to said body,a handle structure pivotally carried by said rigid block, and meanscarried by said handle structure and rigid block and connected to saidslidable block for adjusting the position of the jaw carried thereby.

2. A wrench, comprising a body having a wrench jaw thereon, a blockslidably carried by said body, a wrench aw carried by said block foradjustment relative to the first named wrench jaw, a block. rigidlycarried by said body` a handle pivotally carried by said rigid block, afeed screw adjustable through said rigid block, and an operating rodcarried by said pivotal handle and connected to said feed screw.

In testimony whereof I aHiX my signature.

ANDREW J. KERST-INEE.
